will clean dirty or clogged radiators and cyl inder blocks.

' m A further object is to provide a radiator and cylinder block cleaner which may be used to clean the radiator and cylinder block of an automotive vehicle or water cooled stationary engine without the removal of the radiator and cylinder block, or either of them. .A further object is to provide a radiator and cylinder block cleaner which may be operated in any garage or repair shop that is provided with compressed air and with gowater. v

A. further object is to provide a radiator and cylinder block cleaner which will fit any standard radiator or cylinder block hose connection. L

A further object is to provide such a cleaner sosimple to operate that any ordinary shopman without special experience in cleaning radiators or cylinder blocks may successfully operate it.

in the operation of which no chemical and no boiling process is required.

A further object is to provide such a cleaner which without injury to the radiator will der pressure, whereby a vibratory concussive cleaning effect is produced.

The details of construction by which the above results are obtained are fully described below, and are illustrated in the drawings,

in which Figure'giis an elevation in partial section 53 of our ra ,ator and cylinder block cleaner.

A further object is to provide such a cleaner remove scale, rust, alkali and sediment not Fi re 1. I

igure 3 is a sketch showing one method of using the radiator and. cylinder block cleaner. v

Fi re 4 is a sketch showi another method 0 using the radiator an cylinder block cleaner. a The concussion mixing chamber 1 is ro-.

vided with the threaded water supp y c annel 2, the air supply elf-set 3, the air supply threaded connection 4, and the discharge passage 5. The discharge 1passage wall is tapered and is provided wit a plurality of ridged hubs 6 of difierent diameters, where- 1" by without extra parts or special fittin any of the ordinary-sizes of radiator or cy inder block hose may be directly connected to the" cleaner by the use of the hose clamp already in place on the hose as it is connected in the cooling system of the engine. I I

in Figure 3 the upper radiator hose 7 is connected to the cleaner after being disconnected from the radiatorr The water su ply hose 8is attached to the cleaner by t e '75, ordinary hose connection 9, and the flow of water through the radiator is controlled by the valve 10, which may be in the water supply hoseas shown, or at a more distant point,

as may be desired. so When cleaning a large radiator it may he desired to connect the check valve 11' the water supply line to prevent reverse movement of the water therethrough when the air is a plied.

T is will apply especially where there is a very low pressure on the sup 1y water.

The upper radiator hose% being usually of large size will fit upon one of the larger hubs 6 of the cleaner, the joint being made tight by the hose clamp 7 which was loosened when the hose 7 was removed from the radiator. I

The air hose 11 is connected to the cleaner by the elbow 12 and the ordinary fitting 13. The air valve 14 rests upon the seat 15 and is held thereon resilientlyby the springv16 about the stem 19, andby the button 17 and the cotter pin 18, which passes through the button 17 and the stem 19.

v Fig re 2, is 'a section on the line 2-2 of I m cylinder block and remainder of the cooling In Figure 4 the lower radiator hose 20 is connected to the cleaner after being disconnected from the pump 22, the hose clamp21 mistake.

which was loosened when the hose was removed from the pump being used to make the'jo'int tight.

Since the lower. smaller than the upper hose 7,, it will fit upon one of the smaller hubs6 of the cleaner.

In Figure 3 is shown the method of connecting the radiator and cylinder block cleaner which will generally be found to be sat sfactor It 1s true the scale, rust and sedi-' ment rom the cylinder block is by this connect-ion blown up through the radiator, and at first thought this would appear to be a But, as a matter of actual test, it is found that this method is generally quite satisfactory even though it appears that it should not It is possible that in actual practice the material removed from the cylinder block and the rest of the cooling system and blown through the radiator acts in an abrasive capacity and may aid in the cleaning of the radiator.

In exceptional cases it may be found necessary to make he connection shown in Figure 4; but in a y case for a perfect job the system should be cleaned before the radiator is cleaned and the upper radiator hose left unconnected butplugged till the radiator is cleaned.

Figure l'shows the method to be used only in the. case of a rush job with a large size radiator, orwhere a new cylinder block has been put in a vehicle with an old radiator.

But, even in such a case it would be better to disconnect the hose 7 to prevent material.

from passing from the radiator to the cylinder block during the blowing process.

The operation of our cleaner is as follows Suppose the connection shown in Figure 3 to be used, with the water and the air hose connected to proper sources of supply. The

be left open will depend upon the size of the cooling system and its condition, .as well as upon the number of pounds pressure in the air hose, but is ordinarily about one second.

, In any case, as the water comes from the water hose 1t passes 1nto the concussion mixing chamber 1 andthe tendency is for it to be deflected by the curved walls of the'chamber and to flow ,in a circle as indicatedby the large arrows in Figure 1.

hose 20 is generally,

The length of time the air valve should -When the air valve 14 is opened the air passes about the valve and along the stem 19 as indicated by the small arrows in Figures 1 and 2.

The efi'ect of the off-set of the valve from the smooth inner curve of the interior of the mixing chamber is to spread out the entering air and force it to follow varied paths,

which paths will continue to change as the valve 1 1 is opened wider and wider. The result of this, and of the circular whirling efi'ect given the water supply by its tangential entrance into the mixing chamber, is to form instantly a churned up mlxture of air, bubbles and water. As this passes through-the cooling system it results in a geyser from the radiator as in-- dicated in Figures 3 and 4;, and'the valve 14 should be closed just before the geyser ac-.

tion ceases. This generally means the valve 14 will remain open about one second, which however may vary in diiferent cases as the operator will learn with a little experience.

The water continues to flow. into the system from the water hose, and when the radiator is again fullthe air blast is again applied as before.

This is repeated till the condition of the geyser from the radiator indicates that the cooling system is clean. I

The results obtained from this cleaner are far greater than anyone would suspect before an actual test. Radiators that have already been cleaned by boiling out and by every other method used by radiator repairmen have been connected to this cleaner and without exception it has removed mud, rust, scale and sediment from every supposedly clean radiator that was in "a bad condition before the previous attempted cleaning.

For this reason it is thought that the peculiar construction of the device results not only in a churned up mass of water and air bubbles, but also to some extent in a condition similar in a way to a water hammer, probably due to the intermittent or un-even flow of the water out of the mixing chamber when the air is a lied. water valve 10 is opened up and water flows V pp The self-contained valve and mixing chamber with no flexible and slightly expansible hose between the valve and the chamber gives an instantaneous air ressure efiect in the chamber which undou tcdly greatly assists in the above mentioned action andresults.
